Dial bore gages are available in convenient
sets or with individual probes and dial
indicators. Each set consists of a dial indicator,
a body and actuating rod, two adjusting
wrenches and the probes as specified below.

The head may be ordered separately (includes
dial indicator, body, and two adjusting
wrenches). Individual probes can also be
ordered as listed. All probes are furnished
with an actuating rod. These gages are also
available with electronic indicators by special
order.

Measurements are taken by comparison so
some type of set master should be used as a
reference standard. We recommend setting as
close to the hole being measured as possible,
and this can be easily done with gage blocks
or with a micrometer. We can also furnish
master setting rings – by request.

Features:

The split-ball contact is self-centering and the two-point contact makes the gage useful for detecting hole geometry problems like taper, bell-mouth and out-of-roundness.
